right half of trackpad unresponsive

The right part of my 11" MBA (2010 model) is unable to register clicks, I can't get it to "click" when pressing it. The other half works fine.

There is probably something in the way on the inside, quite annoying. Does anyone know if it's possible to remove the battery so I can push the trackpad a bit up? On my old MacBook Pro I had this problem once, but that had a little screw on the bottom of the trackpad, does the Air have this too?
